Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, a flowchart illustrating steps of a method for protecting a mobile terminal according to an embodiment of the present invention is shown. The mobile terminal is provided with a configuration channel detection module, and the configuration channel detection module is in an uplink port mode, and the method comprises the following steps:
In this embodiment, a configuration channel detection module, that is, a CC detection module, is arranged in the mobile terminal and is used to detect USB connection, detect positive and negative insertions, establish and manage connection between USB devices between data and VBUS, and the like. Referring to the hardware block diagram of the configuration channel detection module shown in fig. 2, when an external device is connected to the CC1 and CC2 pins of the mobile terminal, it can be determined whether the mobile terminal is a master device (Source) or a slave device (Sink) according to the voltages of CC1 and CC 2. For example, when detecting that CC1 or CC2 is grounded through the pull-down resistor Rd, the operation mode of the CC detection module is an uplink port (UFP) mode; when the CC1 or the CC2 is detected to be connected with a 5V power supply through the pull-up resistor Rp, the working mode of the CC detection module is a downlink port (DFP) mode. The CC detection module may switch between the DFP mode and the UFP mode every 50ms, i.e. the operation mode of the CC detection module is a Dual Role Port (DRP) mode. The current detection unit in fig. 2 is configured to determine a current output capability of the mobile terminal according to a resistance value of the pull-up resistor Rp; and determining the current output capability of the external equipment according to the resistance value of the pull-down resistor Rd. Optionally, the usb type-C interface of the mobile terminal is connected to an external device, where the external device includes at least one of an earphone, a display, and a usb disk.
When the mobile terminal is initialized, the working mode of the CC detection module is set to the UFP mode, see the hardware block diagram of the uplink port mode of the configuration channel detection module shown in fig. 3, and the mobile terminal is set as a slave device by default, and can receive data, charge, and the like. And the user switches the working mode of the CC detection module according to the requirement, and the mobile terminal receives the operation instruction of mode switching.
Optionally, a mode switching control is arranged on a display interface of the mobile terminal, and an operation instruction for starting the mode switching control is received. Specifically, a mode switching control may be displayed on a screen of the mobile terminal, where an off state of the mode switching control corresponds to the UFP mode, and an on state corresponds to the DRP mode. And the default of the mode switching control is in a closed state, and when the CC detection module needs to be switched in a mode, the mobile terminal receives an operation instruction for starting the mode switching control.
And step 102, switching the working mode of the configuration channel detection module from the uplink port mode to a dual-role port mode according to the operation instruction.
In this embodiment, after receiving an operation instruction for mode switching of the CC detection module, the working mode of the CC detection module is switched from the UFP mode to the DRP mode. Referring to fig. 2, when the CC detection module is in the UFP mode, the switch connects the pull-down resistor and the CC pin together; when the CC detection module is in a DRP mode, the switch is periodically switched between the connection of the pull-down resistor and the CC pin and the connection of the pull-up resistor and the CC pin.
And 103, when the service state of the mobile terminal is detected to meet a preset condition, switching the working mode of the configuration channel detection module from the dual-role port mode to the uplink port mode.
In this embodiment, the CC detection module is in the DRP mode, and the mobile terminal may serve as a master device to transmit data to an external device and charge the external device; the mobile terminal can also be used as a slave device to charge the mobile terminal. And when detecting that the use state of the mobile terminal meets a preset condition, switching the working mode of the CC detection module from the DRP mode to the UFP mode. Optionally, the preset condition includes at least one of that the configuration channel detection module is in the dual-role port mode and the duration of the configuration channel detection module not serving as a master device exceeds a set duration or that an operation instruction for closing the mode switching control is received. For example, if the CC detection module is in the DRP mode and the duration that the mobile terminal is not used as the master device exceeds the set duration by 5min, the operating mode of the CC detection module is switched to the UFP mode. The set duration is not limited in detail in the embodiment of the invention, and can be set according to actual conditions.
In summary, in the embodiments of the present invention, the mobile terminal is provided with the configuration channel detection module, and the configuration channel detection module is in the uplink port mode. When the mobile terminal receives an operation instruction for switching the mode of the configuration channel detection module, the working mode of the configuration channel detection module is switched from the uplink port mode to the dual-role port mode according to the operation instruction, and at the moment, the mobile terminal can be used as a slave device or a master device, and can be used as the master device for transmitting data to an external device or supplying power to the external device. And when the condition that the state of the mobile terminal meets the preset condition is detected, the working mode of the configuration channel detection module is switched to an uplink port mode from a double-role port mode, namely the mobile terminal is switched to a slave device, and charging can be carried out. Because mobile terminal defaults as the slave unit, therefore can avoid impurity or liquid to get into the USB Type-C interface and the mode of misjudgment configuration passageway detection module that leads to, the unable problem of charging of mobile terminal.
